A drawing design of the N&W class J locomotive. After the outbreak of World War II, the Norfolk and Western Railway's (N&W) mechanical engineering team developed a new locomotive—the streamlined class J 4-8-4 Northern—to handle rising mainline passenger traffic over the Blue Ridge Mountains, especially on steep grades in Virginia and West Virginia.
Nos. 611 to 617 were a larger development of the earlier 601 class locomotives. They were fitted with a Deutz F/A8L 714 engine of 120 kilowatts (160 hp), with Voith hydraulic transmission, weighed 22 tonnes (22 long tons; 24 short tons) and had a maximum speed of 42 kilometres per hour (26 mph).
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. [1] Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country.
For a list of locomotive types or models, please see List of locomotive classes. A list of locomotive classes that have a corresponding Wikipedia article. A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually referred to as a multiple unit ...
See wheel arrangement, UIC classification, Whyte notation and AAR wheel arrangement. Sub-categories in this section include articles about different classes of locomotive with the same wheel configuration. Wheel numbered articles provide overall info for trains of that type.

The MOW crew had to disconnect the locomotive from its tender and rerail it one set of wheels at a time. [9] On the afternoon of January 26, No. 611 was finally back on the rails and towed to Williamson for inspection. [5] [9] The locomotive's skirting panels, running boards, valve gear parts, and other appliance parts were torn off from its ...
Thus, a Union Pacific Big Boy is a 4-8-8-4: four leading wheels, one group of eight driving wheels, another group of eight driving wheels, and then four trailing wheels. Sometimes articulated locomotives of this type are denoted with a “+” between each driving wheels set (so in the previous case, the Big Boy would be a 4-8+8-4).
